The battery charge-control indicator g indicates the charging
progress. During the charging procedure, the segments flash
one after the other. When all segments of battery charge-con-
trol indicator g are displayed, the battery is completely
charged.
Disconnect the battery charger from the mains supply when
not using it for longer periods.
Additionally, the battery can also be recharged via a USB port.
For this, connect the measuring tool to a USB port using the
micro USB cable. In USB operation (recharging, data trans-
mission), the charging duration n can be significantly pro-
longed.
The measuring tool cannot be used independently during the
charging procedure. Usage is possible only in combination
with a USB connection and the available software.
The Bluetooth® function switches off during the charging pro-
cedure. Existing connections to other devices are interrupt-
ed. This can lead to data loss.
 Protect the battery charger against moisture!
Notes for Optimum Handling of the Battery in the Measur-
ing Tool
Store the measuring tool only within the allowable tempera-
ture range, see "Technical Data". As an example, do not leave
the measuring tool in a vehicle in summer.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.
Operation
Initial Operation
 Do not leave the switched on measuring tool unattend-
ed and switch the measuring tool off after use. Other
persons could be blinded by the laser beam.
 Protect the measuring tool against moisture and direct
sun light.
 Do not subject the measuring tool to extreme tempera-
tures or variations in temperature. As an example, do
not leave it in vehicles for long time. In case of large varia-
tions in temperature, allow the measuring tool to adjust to
the ambient temperature before putting it into operation.
In case of extreme temperatures or variations in tempera-
ture, the accuracy of the measuring tool can be impaired.
 Avoid heavy impact to or falling down of the measuring
tool. After severe exterior effects to the measuring tool, it
is recommended to carry out an accuracy check (see "Ac-
curacy Check and Calibration of the Grade Measurement"
and "Accuracy Check of the Distance Measurement" on
page 17) each time before continuing to work).
Switching On and Off
For switching on the measuring tool, the following possibili-
ties are given:
– Press the On/Off button 4: The measuring tool is switched
on and is in length measurement mode. The laser is not ac-
tivated.
2 609 141 148 | (24.1.14)
– Pressing the measuring button 2: Measuring tool and laser
are switched on. The measuring tool is in length measure-
ment mode. When the measuring tool is inserted in the
measuring rail 27, the grade measurement function is acti-
vated.
 Do not point the laser beam at persons or animals and
do not look into the laser beam yourself, not even from
a large distance.
To switch off the measuring tool, press the On/Off button 4
for a few seconds.
When no button on the measuring tool is pressed for approx.
5 minutes, the measuring tool automatically switches off to
save the batteries/rechargeable batteries.
When the angle is not changed for approx. 5 minutes when in
the "Grade measurement" operating mode, the measuring
tool automatically switches off to save the batteries/re-
chargeable batteries.
When switching off automatically, all stored values are re-
tained.
Measuring Procedure
When the measuring tool is inserted in the measuring rail 27,
it is always in the length measurement or grade measurement
function after switching on by pressing the measuring button
2. Other measuring modes can be switched to by pressing the
respective function/mode button (see "Measuring Func-
tions", page 13).
After switching on, the rear edge of the measuring tool is pre-
set as the reference level for the measurement. By pressing
the reference level button 10, the reference level can be
changed (see "Selecting the Reference Level", page 13).
Place the measuring tool with the selected reference plane
against the desired starting point of the measurement (e.g. a
wall).
Briefly press the measuring button 2 to switch on the laser
beam.
 Do not point the laser beam at persons or animals and
do not look into the laser beam yourself, not even from
a large distance.
Aim the laser beam at the target surface. Briefly press the
measuring button 2 again to initate the measurement.
When the laser beam is switched on permanently, the meas-
urement already starts after the first actuation of the measur-
ing button 2. In continuous measurement mode, the measure-
ment starts immediately upon switching on.
Typically, the measured value appears after 0.5 and latest af-
ter 4 seconds. The duration of the measurement depends on
the distance, the light conditions and the reflection proper-
ties of the target surface. The end of the measurement is indi-
cated by a signal tone. The laser beam is switched off auto-
matically upon completion of the measurement.
When no measurement takes place approx. 20 seconds after
collimating, the measuring tool automatically switches off to
save the battery.
